Cyclohexane is a clear, colorless, flammable liquid with a mild, sweet, detergent-like odor. It is a saturated cyclic hydrocarbon (alkane) with the molecular formula C₆H₁₂, consisting of a ring of six carbon atoms, each bonded to two hydrogen atoms. Cyclohexane is primarily produced through catalytic hydrogenation of benzene and is widely used both as a solvent and a chemical intermediate.

It is insoluble in water but miscible with most organic solvents, making it ideal for a wide range of industrial applications where non-polar solvents are required.
